    Fire curtains

    Fire curtains separate fire compartments, slowing the spread of fire in a warehouse, production hall, shopping centre or car park for 15 to 120 minutes.

    Smoke barriers

    Smoke barriers divide a space into several smaller smoke zones. These are then easier to ventilate using a smoke and heat exhaust ventilation system.

    Smoke ventilation

    Smoke and heat exhaust ventilation minimises property damage, makes it easier for firefighters to intervene and gives people enough time to leave the building safely.

KA 66-TW

MOST POWERFUL UNIVERSAL CHAIN DRIVE 24 V
Category:

Doubled pull and push force with the same load distribution on the window sash: our KA 66-TW chain drive for smoke and heat exhaust ventilation combines two KA 34 drives in one unit. For simplified installation and low maintenance and service costs.

KA 66-TW

Features

  • Can be used for smoke exhaust openings, D+H Euro SHEV to EN 12101-2, and for daily ventilation.
  • With an integrated BSY+ motor and microprocessor-controlled synchronised electronics.
  • High-speed function (HS) for exceptionally fast window opening in the event of fire (SHEV).
  • Two drive chains for optimum force application to the sash
  • Special chain stabilisation
  • Pressure relief on the window seal after closing
  • Electronic force and position control
  • Programmable drive functions and various drive parameters
  • Travel speed in the CLOSE direction drops to 5 mm/s (passive closing edge protection)
  • Timed reversing when an obstacle is detected in the CLOSE direction (active closing edge protection).
  • Available in any RAL shade
  • Can be used for practically all types of window openings
  • The drive is suitable for surface mounting on the window sash or frame
  • Thanks to universal brackets, the drive is compatible with almost all available types of system profiles incl. Aluprof, Colt, Gutmann, Heroal, Jet-Brakel, Raico, Reynaers, Sapa, Schüco, Skandinaviska, Technal, Wicona

Optional extras

  • Function programming
    The option of configuring drive parameters (e.g. the stroke) individually using software and the related service tools, for drives fitted with PLP, BSY or BSY+ electronics.
  • BRV signal
    Confirmation from the drive, via the control cable, that the drive has fully extended or retracted. When used with the AT 41 and ERM 44 modules, this signal is sent to the central building management system, to the modules themselves or to the locking drive. The BRV signal is not potential-free.
  • SGI signal (position reporting)
    In combination with the D+H servo plug-in unit SE 622 or the BSY gateway BSY-GW-024-010-U, drives can be controlled with precise positioning.
  • SKS (closing edge protection)
    An optional function that allows an “anti-trap” safety edge or a presence detector to be connected directly to the drive (terminating resistor 5.6 kΩ).
  • Acoustic signal (corresponding to the protection class)
    AS2 corresponds to “protection class 2” of the ZVEI risk assessment by means of an acoustic warning signal in the “CLOSED” running direction. AS3 corresponds to “protection class 3” of the ZVEI risk assessment: in addition to AS2, it stops the drive for 11 s with a remaining stroke of 28 mm.
  • End position signal (OPEN / CLOSED)
    Feedback from the drive via an integrated potential-free switching contact. It is given when the chain drive or linear drive has fully extended or retracted.
  • SBD (bendable chain)
    The drive chain with a rigid back bends in the direction of the hinges. The drive is fixed in place (it does not pivot).
  • SBU (bendable chain)
    The drive chain with a rigid back bends in the direction of the hinges. The drive is fixed in place (it does not pivot).
